Nonviral vectors that harness the change in pH in endosomes, are increasingly being used to deliver cargoes, including nucleic acids, into mammalian cells. Here we present evidence that the pK(a) of the beta-NH(2) in 2,3-diaminopropionic acid (Dap) is sufficiently lowered

Capreomycin is an important therapeutic agent having intriguing and diverse molecular features. Its polypeptidic structure rich in nitrogen donors makes the drug a promising chelating agent for a number of transition metal ions, especially for copper(II). The results of the
An efficient enantioselective synthetic method for (S)-alpha-alkyl-alpha,beta-diaminopropionic acid is reported. The asymmetric phase-transfer catalytic alkylation of N(1)-Boc-2-phenyl-2-imidazoline-4-carboxylic acid tert -butyl ester in the presence of chiral quaternary ammonium catalyst gave the corresponding alkylated products (93-98% ee) which could be transformed

A novel and convenient route to the asymmetric synthesis of 2,3-diamino acids via Mannich reaction of iminolactones 1a and 1b with N-protected imines has been achieved in good yields (up to 95%) and high diastereoselectivity (dr: >99:1). Hydrolysis of the
Here we report a novel class of peptides-d-diaminopropionic acids (Dap)-for gene delivery. These peptides have attractive properties for gene delivery, and the advantage that they can be easily manipulated in relation to their composition, abiding with tailored-design. We characterized the
